post Reduced incidence of atopic dermatitis in children whose mothers consumed probiotics w
If a healthy mother consumes probiotics in the perinatal period, does it affect allergy-related diseases in her child at six years of age?
In this study, 415 pregnant women were randomised to consume either probiotic or placebo milk from 36 weeks gestation until 3 months postpartum. The probiotic milk contained three strains: Lactobacillus rhamnosus GG, L. acidophilus La-5, and Bifidobacterium animalis subsp. lactis Bb-12.
At six years, the children whose mothers consumed probiotics showed a trend toward lower cumulative incidence of atopic dermatitis (AD), compared with children whose mothers were in the placebo group. Maternal probiotics did not seem to affect the prevalence of asthma, atopic sensitisation, or allergic rhinoconjunctivitis in these children.
This evidence agrees with previous research reporting fewer cases of AD at two years, after maternal probiotic supplementation. The study goes further, showing that maternal probiotics may be sufficient for a long-term reduction in children’s incidence of AD. However, maternal perinatal probiotics may not affect other allergy-related diseases.
